I'm another one who's a sucker for the doctors, because... well, I'm me.

original 'verse McCoy - old-fashioned country doctor with both skill and heart for days
Bashir - he can zip it when he's being earnestly eager, but his professional modes are amazing
Pulaski - craggy exterior with a heart of gold
Crusher
holographic Doctor

I don't know Phlox or the AU McCoy well enough to really judge. I would love to know Excelsior's CMO. ... Heck, I'd love to know Excelsior's whole crew!
